sediments of the nezam-abad area, south-east of bam have been studied for the first time. sedimentary facies are composed of thin-bedded clay, silt and fine grained sand interbedded with thin laminated limestone. chemical analysis of x-ray florescent indicates that more than 50% of sediments consist of silisium and aluminum oxide that can be used for reconstruction of environment. ninety eight ...

periodic vehicle routing problem focuses on establishing a plan of visits to clients over a given time horizon so as to satisfy some service level while optimizing the routes used in each time period. this paper presents a new effective heuristic algorithm based on data mining tools for periodic vehicle routing problem (pvrp). the related results of proposed algorithm are compared with the resu...

the effect of external magnetic and electric fields, in the range of electroporation and magnetoporation, on lucifer yellow (ly) fluorescence in the absence of cells is studied. electric-field-induced quenching and magnetic field-induced increase are observed for fluorescence intensity of ly. regard to the fact that the variation of field-induced fluorescence, even in the absence of cells, can ...

The present paper is an attempt to develop a new heuristic algorithm, find the optimal sequence to minimize the utilization time of the machines and hence their rental cost for two stage specially structured flow shop scheduling under specified rental policy in which processing times and set up time are associated with their respective probabilities including transportation time. Further jo...

Although timing deficits are a robust finding in schizophrenia (SZ), the notion of a genuine time perception disorder in SZ is still being debated because distortions in timing might depend on neuropsychological deficits that are characteristics of the illness. Here we used meta-analytic methods to summarize the evidence of timing deficits in SZ and moderator analyses to determine whether defec...

educational evaluations reveal degrees of value creation for stakeholders. the evaluation results can help to improve the quality of teaching and prevent to wasting educational efforts. in this study, using the kirkpatrick model (1994), the effectiveness on management development curriculums of the levels behavioral / applicable in descriptive and quasi- experimental method has been studied. sh...

In this article, we use longitudinal morphometry (shape and size) measures of hippocampus in subjects with mild dementia of Alzheimer type (DAT) and nondemented controls in logistic discrimination. The morphometric measures we use are volume and metric distance measures at baseline and follow-up (two years apart from baseline). Morphometric differences with respect to a template hippocampus wer...
